I don't know what 'stfp' means, but, yeah... there's definitely some kind of thing going on with Myaako and Shirogane... but Shirogane also started crushing on Ginga since this stuff presumably went down, so, uh... pretty sure not happening until she gives up on Ginga, but we haven't really done anything with Ginga and Aya or any other potential pairings around the bathhouse neighborhood for awhile.
And yeah, Kaguya and Inukai Hakase are pretty cool. (fyi, I keep a character reference on hand to remind me of everybody's names)
Oh, and before I forget, the splash art text appears to say: "The flower language of yellow roses is friendship." Nothing about lillies in there, it seems, so maybe we should dial back the assumptions.
